WordPress is a widely used CMS (Content Management System) application, which is based on PHP and MySQL. It is the most popular and the simplest way of creating a website or a blog.


The guide outlines the basic steps of installing WordPress application in an Ubuntu server, assuming that the server already has a web service (Apache), database service (MySQL/MariaDB) and PHP installed in it.


Create WordPress database

The first step before installing WordPress on the server would be to create a database that would be used to store the WordPress data.


  1. Log in to the database server by executing the below command.

    # mysql -u root -p
    

    wordpress1

  2. Create the WordPress database and an associated database user.

    # CREATE DATABASE lswp_db;
    
    # CREATE USER 'lswp_usr'@'localhost' IDENTIFIED BY 'wpusrpwd';

    NOTE: lswp_db is the database name, lswp_usr is the database user associated with lswp_db and wpusrpwd is the password for the user lswp_usr.

  3. Grant permissions for the database user to access the WordPress database.

    # GRANT ALL ON lswp_db.* TO 'lswp_usr'@'localhost' IDENTIFIED BY 'wpusrpwd';

  4. Exit the MySQL/MariaDB database server.

    # FLUSH PRIVILEGES;
    
    # quit;

Installing WordPress

For installing WordPress, the latest WordPress installation archive file first needs to be downloaded. This can be done from the official WordPress downloads page https://wordpress.org/download/.


  1. Navigate to the path under which the WordPress application is to be installed. This can be under the default document root of the web service or under any website.

    In the below example, WordPress is being installed under the default document directory of Apache /var/www/html/.

    # cd /var/www/html/

  2. Download the latest WordPress installation archive file.

    # wget https://wordpress.org/latest.tar.gz
    

    wordpress6

  3. Extract the tarball latest.tar.gz, which will create a folder named “WordPress” containing the installation files.

    # tar -xvf latest.tar.gz
    

    wordpress7

  4. Update ownership of the WordPress folder and all files inside it.

    # chown -R www-data:www-data /var/www/html/wordpress
    

    wordpress8

    Here, www-data is the user that the Apache webserver runs as. If WordPress is being installed under a website, then the owner needs to be updated using the username associated with the website.

  5. Execute below two commands to set the required permissions for the wordpress folder and files and folders inside it.

    # find /var/www/html/wordpress/ -type d -exec chmod 755 {} \;
    
    # find /var/www/html/wordpress/ -type f -exec chmod 644 {} \;

  6. The WordPress installation page can now be browsed using a browser.

    http://ipaddress/wordpress (if wordpress installed under default directory)
    (or)
    http://websitename/wordpress (if wordpress installed under a website)
